I really liked this book! Read it in 3 sittings. Author takes on a journey and his philosophy in simplifying his life by getting rid of many of his extra belongings and improving other areas (healthy eating, etc).

Includes 55 Tips to say goodbye to your things, and 15 tips for the next phase of one's minimalistic/simple journey.

Does not encourage straight out trash, but does recommend auctions and donations.

This had been on my list for a while and I'm really glad I read it. Encourages me to get rid of some stuff.

I'd love to see a followup or yearly update of how he's doing. He does run a blog but it's in Japanese.
